Interconnection costs can significantly impact the financial viability of your distributed generation (DG) project. At Electric Peak Engineering, we understand the complexities of the interconnection process and provide expert analysis to help you navigate these expenses. This section offers resources and insights into understanding and managing interconnection costs. 

Federal Energy Regulatory Commission (FERS)
The FERC regulates the interstate transmission of electricity, natural gas, and oil, and plays a key role in ensuring fair and efficient wholesale energy markets. FERC also establishes rules and orders impacting the interconnection and participation of Distributed Energy Resources (DER) in those markets.

Key Regulatory Orders

Understanding key regulatory orders is essential for navigating the complexities of DER interconnection and participation. This section highlights critical regulations impacting your project. 

FERC Order No. 2222: Enabling DER Participation in Electricity Markets
FERC Order No. 2222 is a landmark ruling that paves the way for distributed energy resources (DERs)—like solar, energy storage, and demand response—to fully participate in wholesale electricity markets. This order breaks down barriers, allowing these resources to be aggregated and compete on a level playing field with traditional power plants. By enabling DER participation, FERC Order No. 2222 aims to enhance grid reliability, increase competition, and drive innovation in the energy sector. This is a crucial development for anyone involved in DER projects, as it creates new opportunities for revenue generation and grid services.
